IA. Analysis of Solar Active Regions and Activity from 27/2100Z to
28/2100Z: Solar activity has been at very low levels for the past 24
hours. A 10 degree filament, centered near N08E20, was observed erupting
in H-alpha imagery beginning at 27/1939 UTC. STEREO-A COR2 imagery
showed an associated faint CME beginning at 27/2309 UTC with the
majority of the ejecta directed north of the ecliptic. We are
currently waiting on further imagery to determine possible
geoeffectiveness. There are currently 4 numbered sunspot regions on the
disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (29 Dec,
30 Dec, 31 Dec).

IIA. Geophysical Activity Summary 27/2100Z to 28/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 314 km/s at
28/0506Z. Total IMF reached 6.2 nT at 28/1254Z. The maximum southward
component of Bz reached -5.3 nT at 28/1804Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for the next three days (29 Dec, 30 Dec, 31 Dec).
